Edison, 23, originally signed on to the Bears’ practice squad during last season as an undrafted free agent out of Portland State. He was brought back on a future/reserve contract a few months later.

However, the Bears elected to cut Edison loose coming out of the preseason. Chicago later signed him to their practice squad right before the start of the regular season before promoting him to their active roster.

The Bears just waived Edison again, only to re-sign him to their practice squad less than a week later.

Edison has been active for one NFL game.

Richardson, 25, is a former fourth-round pick by the Bills in the 2014 NFL Draft. He was signed to a four-year, $2.412 million rookie contract that included a $192,000 signing bonus and was set to make a base salary of $600,000 this season.

The Bills made him one of their final roster cuts coming out of the 2015 preseason and later signed to a future/reserve deal back in January. However, he was unfortunately among the team’s final roster cuts as they trimmed down to the 53-man limit.
